Hello from MrBillDoesMath!
Answer:
See Discussion below.
Discussion:
1/2 = x - 3/4 => add 3/4 to both sides
1/2 + 3/4 = x - 3/4 + 3/4 => as -3/4 + 3/4 = 0
1/2 + 3/4 = x + 0 =>
x = 2/4 + 3/4
x = 5/4 = 1-1/4
Thank you,
MrB
1) -10x+y=4
Now, you should substitute x in every situation.
* x=-2 <em>=> -10*(-2)+y=4... 20+y=4... <u>y=-16</u></em>
<em />* x=-1 =>-10*(-1)+y=4... 10+y=4... <u>y=-6</u>
<u />*x=0 => -10*0+y=4... <u>y=4</u>
<u />* x=1 => -10*1+y=4... -10+y=4... <u>y=14</u>
<u />* x=2 => -10*2+y=4... -20+y=4... <u>y=24</u>
<u>2)</u> -5x-1=y
For example: x=0
-5*0-1=-1

<span><span>From the choices the answer is c. 27π m2
<u>Explanation</u>
</span><span>The formula for calculating the area of a circle is;
Area = πr^2
Where π = 3.142
r = radius of the circle.
When a sector of the circle is involve area is a fraction of the whole circle and it is given by;
Area of a sector = θ/360 πr^2
Where ϴ = angle that makes the sector
So, area = 120/360 π9^2=</span>27π

Answer:
the answer is D: (x2 + 7x + 3) square inches.
Step-by-step explanation:
the window is shaped like a rectangle, so the formula for area is simply length x width.
